8 - 11 indicates alkalinity. 12 - 14 indicates a very high level of alkalinity. press the testing strip to the object or liquid you are testing. Half second later, take out the paper and using the color chart included, compare the color change of the paper to find out the acidity level of your testing subject.

Litmus papers are used to determine the pH level of a liquid and determine if a solution is acidic, basic, or neutral. Widely used for industrial chemical testing, science education, laboratory use, drinking water, swimming pool, spas, aquariums, and classroom analytical chemistry.SpecificationAccuracy: 0.5 pHTesting Range: 0.5-5Testing Paper Size: 54mmx9mm (L*W)Overall Size: 70mmx45mmx5mm (L*W*H)Packing List: 4 x Litmus Test Kit (80/Pack,320pcs)AdvantageThere are 10 color-coded scales that go from 0.5 to 5. Also can be used to determine the strength of acid and base, as we go from 5 to 1 the acidity of the solution increases.InstructionDipping the pH paper into a solution and observing the change in color of the paper. After one second, compare it with the standard color cards and read the pH value.

The test strip color changes must be matched with the pH scale color chart within about 15 seconds. Different pH content discoloration range is different, by comparing the color card ratio: the smaller the number, the stronger the acidity, the larger the value, the stronger the alkalinity.
